The prevalence of diabetic retinopathy in patients with screen-detected type 2 diabetes in Denmark: the ADDITION study.

Background: The prevalence of type 2 diabetes is increasing, but the exact prevalence of the disease and its accompanying late complications are unknown. In the Anglo-Danish-Dutch study of Intensive Treatment in People with Screen-detected Diabetes in Primary Care (ADDITION study), patients with hitherto undiagnosed type 2 diabetes are identified using a stepwise screening strategy in selected general practices. This article reports the occurrence of diabetic retinopathy in this population.

Screening for diabetic retinopathy in Denmark: the current status.

Purpose: To investigate the current status of screening for diabetic retinopathy in Denmark, focussing on organization, methods of screening and regional differences.

Methods: A questionnaire was sent out in 2002 to 14 departments of ophthalmology and one ophthalmology practice, covering all 15 counties in Denmark.

Results: Six counties reported having systematic screening, defined as organized screening, including a database; three reported having plans for systematic screening; two reported having undetermined plans for systematic screening and four reported having no plans for systematic screening.
